“…LA implant fractures are more likely to occur when opposing implant-supported prostheses. This might be attributed to the higher rigidity exerted by the LA implant (cp Ti grade 4) (Eckert et al, 2015) and reduced proprioceptive feedback from the opposing implant-supported restoration (Koyano & Esaki, 2015).…”

“…Moreover, it is considered a multifactorial failure resulting from a chain reaction of a combination of biological (i.e., peri-implantitis) and mechanical complications (Goodacre et al, 1999). Occlusal overload due to bruxism or inappropriate occlusion may also induce implant failure (Stoichkov & Kirov, 2018), manifesting as accumulative metal fatigue (Eckert et al, 2015;Shim & Yang, 2015). Assuming that the overall external load is constant, the distribution of stress over the prosthesis-abutment-implant-adjacent bone complex is determined by the geometric configuration and physical properties of the implant components (crown material, abutment, fixture, and abutment-implant interface), as well as bone quality (Eckert et al, 2015).…”

“…Once the amount of stress exceeds the fracture resistance, a fracture occurs at the point of weakness. Therefore, fractures have recently been considered as mechanical sequelae (Eckert et al, 2015). Consequently, the long-term stability of the implant-abutment complexes, which determines the success of the restoration, remains an issue.…”

Objective To evaluate the long‐term integrity of implant–abutment complexes in implant systems with two internal conical angles. Material and Methods 12,538 bone‐level implants of two systems placed between January 2012 and December 2018 were retrospectively analyzed. Cumulative abutment/implant fracture rates in systems with larger (LA, 7.5°) and smaller (SA, 5.7°) internal conical angles were estimated using the Kaplan–Meier analysis and compared between groups. The association between implant systems and jammed abutment retrievability was evaluated by multivariable generalized estimating equation logistic regression modeling. Results For LA, the 8‐year cumulative incident rate was 0.10% (95% confidence interval (CI): 0–0.24%) for implant fracture and 0.26% (95% CI: 0.11%–0.41%) for abutment fracture, demonstrating a significant difference in gender (p = .03), implant diameter (p = .01), jaw (p = .006), and antagonist tooth (p < .001). For SA, the 8‐year cumulative incident rate was 0.38% (95% CI: 0–0.79%) for implant fracture and 2.62% (95% CI: 0.05%–5.13%) for abutment fracture, which was influenced by implant diameter (p < .001) and site (p = .03). The cumulative implant/abutment fracture rate was lower for LA implants, particularly for LA implant‐supported single crowns (SCs) (p < .05). The abutment‐retrieval success rate was 92.9% for LA and 57.1% for SA (p = .055). Conclusion LA implants exhibited a lower incidence of fracture in abutment–implant complexes and a relatively higher retrievability success rate for jammed abutments.

“…Implant fracture is rare, [13][14][15] and it occurs with narrow diameter implants specifically where the bony wall is thin. 13 For instance, at the implant level, Eckert et al 16 found that implant fracture occurred more frequently in partially edentulous prostheses (1.5% incidence) than in completely edentulous ones (0.2% incidence), and all fractured implants were of narrow diameter 3.75 mm.…”

Aim: The aim of this study was to detect and analyze dental malpractice in the field of implant dentistry in the Kingdom of Saudi Arabia. Materials and Methods: 106 patients aged ≥ 18 years with at least one professional malpractice in implant dentistry done in dental health premises in Saudi Arabia were included in the study. Clinical and radiographic examinations were used to detect preoperative (diagnosis and treatment planning), intraoperative (implant insertion), and postoperative (post surgery and prosthesis) complications. The data obtained including age and gender were documented in a patient examination form then statistically analyzed using Chi-Square Test and Spearman’s Correlation Coefficient. Results: The percentages of patients were equally divided among the preoperative, intraoperative, and postoperative phases p > 0.05. More than half of the patients were females (61.3%). The majority of the patients were in the age group 50-60 years. Also, the majority of the patients had implants with malpractice placed in the posterior region. Exactly half of the patients had implants with malpractice placed in the maxilla. In addition, exactly half of the patients had technical errors violating the surrounding structures; (37.7%) of the patients had damage to adjacent tooth and (11.3%) had inferior alveolar nerve damage; also, (4.7%) of them had sinus penetration. Furthermore, at the patient level, age and gender were not related to implant failure, and (75.5%) of the patients had implant failure. With respect to peri-implantitis, patients ≥ 50 years of age were more than patients < 50 years of age. However, gender and maxilla were not related to peri-implantitis. The prevalence of peri-implantitis was 20.8% at the patient level. In partially edentulous patients, implant fracture was (1.17%) at the implant level. Conclusion: Implant malpractice equally occurred among the preoperative, intraoperative, and postoperative phases. Keywords: Failure, Implant, Intraoperative, Malpractice, Peri-implantitis, Postoperative, Preoperative.

“…Previous studies indicated several contributors for implant fracture: (1) inappropriate implant material [8] , (2) bad implant designs [13] , (3) inappropriate fixator selection [10] , [14] , (4) inappropriate surgical technique [9] , (5) and (6) biomechanical overload [15] , [16] . These factors are deleterious for implants fatigue resistance, which eventually lead to fracture.…”

HighlightsThe dynamic load was generated at basitemporal skull if prosthesis was not anchored to this loci.Via the parietal tuber-temporozygomatic suture line, this dynamic load was passed to the proximal pterion point region, which eventually generated fatigue effects on the prosthesis and eventually fracture.The cranioplasty prosthesis shall be well anchored onto the basitemporal skull to prevent fatigue effects of the prosthesis.
